Differences between lithium battery and lithium-ion battery

1. The 18650 battery is cylindrical with transparent liquid inside. This is due to the battery concept and material. 18650 is suitable for high current, so that almost all laptops and electric cars are basically designed with 18650 batteries; only super notebooks, This is due to environmental protection and energy saving, so polymer lithium-ion batteries can be used instead of 18650 batteries, especially for tablet computers, etc. Digital cameras are due to the large voltage and instantaneous high current required for charging and discharging of the photo flash, so only 18650 can be used. Similar batteries, only slightly smaller;

The battery manufacturing process is mainly divided into two technical routes: lamination process and winding process. At present, the main technical direction of Chinese battery enterprises is mainly around winding, but with the progress of lamination technology, a large number of battery enterprises begin to enter the lamination field.

The service life of lithium battery is an index that must be paid attention to in the use of lithium ion battery. Generally speaking, the service life of lithium ion battery is mainly affected by two factors: 1) service time; 2) Number of cycles.

The electrolyte is a conductive ionic conductor between the positive pole and the positive pole of the battery. It is composed of electrolyte lithium salt, high-purity organic solvent, necessary additives and other raw materials in a certain proportion. It plays an important role in the energy density, power density, extensive temperature applications, cycle life and safety performance of batteries.
